    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

    Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

  • Primary antibody说明

    GTPase Activating Protein (GAP) is capable of stimulating the hydrolysis of GTP by ras p21 proteins, though GAP has little effect on the oncogenic forms of ras. It is also known that several tyrosine kinases such as platelet derived growth factor receptor and epidermal growth factor receptor are involved in the tyrosine phosphorylation of GAP. It has therefore been suggested that GAP may provide a connection or link between growth factor receptors and the ras p21 family.

应用

Our Abpromise guarantee covers the use of ab2922 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
ICC/IF Use a concentration of 5 µg/ml.

Immunofluorescence staining of GAP in mouse fibroblast cells results in diffuse cytoplasmic staining. Following the addition of PDGF, immunofluorescence staining shows that some GAP rapidly translocates to the plasma membrane.
WB Use a concentration of 10 µg/ml.

By Western blot, this antibody recognizes a single 120 kDa protein representing ras GAP from RS-2 cell lysate.

靶标

  • 功能

    Inhibitory regulator of the Ras-cyclic AMP pathway. Stimulates the GTPase of normal but not oncogenic Ras p21.

  • 组织特异性

    In placental villi, detected only in the trophoblast layer (cytotrophoblast and syncytiotrophoblast). Not detected in stromal, endothelial or Hofbauer cells (at protein level).

  • 疾病相关

    Note=Mutations in the SH2 domain of RASA seem to be oncogenic and cause basal cell carcinomas.
    Defects in RASA1 are the cause of capillary malformation-arteriovenous malformation (CMAVM) [MIM:608354]. CMAVM is a disorder characterized by atypical capillary malformations that are multiple, small, round to oval in shape and pinkish red in color. These capillary malformations are associated with either arteriovenous malformation, arteriovenous fistula, or Parkes Weber syndrome.
    Defects in RASA1 are a cause of Parkes Weber syndrome (PKWS) [MIM:608355]. PKWS is a disorder characterized by a cutaneous flush with underlying multiple micro-arteriovenous fistulas, in association with soft tissue and skeletal hypertrophy of the affected limb.
